alertdialog role (aria)

Support level: supported

On this page

A type of dialog that contains an alert message, where initial focus goes to an element within the dialog. See related alert and dialog.


Expectations are conditions that must be met for the feature to be considered as "supported". Only "MUST" expectations need to be met for minimal "support". "SHOULD" and "MAY" expectations indicates support that goes above and beyond. Note that there is not an explicit standard that dictates these expectations, and as such, they are likely opinionated. As such, a feature might not meet all "MUST" expectations but still be usable (potentially frustratingly so). Additionally, the assistive technology may provide many different commands to read, navigate, or otherwise interact with a feature. Only one command is required to pass for the expectation to be minimally supported.
